Back in the early 2000s, the tech term radio frequency identification (RFID) became much better known to people in business because big players in supply chains including Walmart and the U.S. Department of Defense were piloting RFID technology to track inventory. The thinking then was that with such major players pushing RFID, it would soon become a mainstay method of tracking goods in supply chains, perhaps even eclipsing the bar code.
